Formula and Step-by-Step
- Start with 18 ounces of raisins
- Convert ounces to grams: 18 × 28.35 = 510.29g
- 1 cup of raisins = 145g

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
To prevent dried fruit from sinking in batter, toss it with a tablespoon of flour before folding in. This does not affect the weight measurement.
